How long does it take to run? Does it vary between XT32/SubEQ and other Audyssey flavors? My Yamaha A3040 takes probably 3 minutes to run YPAO if I skip the angle measurements using the boomerang device.

Everything I have read is if you use an external calibration device, whether it is a MiniDSP, Anti-Mode, etc, you always re-run your automatic correction program after. Correct me if I'm wrong, but the theory is to leverage more resolution ability. If my receiver can only calibrate the subs on 4 different frequencies, then using the Anti-Mode's 36 filters to pre-correct the response allows for more of a "flattening potential" to the correction after the fact.

Now that I have a mic stand to attach the Audyssey mic to (rather than monkey around with some home-made/pain-in-the-ass microphone holder), I can get all 8 positions measured and calibrated in about 20 mins.

That Anti-Mode seems well reviewed and a worth while investment ... I'm curious too as to if and when you might incorporate the YPAO I'm guessing run the YPAO initially, if at all.

I finally have the new theater up and running, along with my dual PC-12 Plus and PC-13 Ultra. I must say that I am very impressed. While the bass doesn't seem much louder necessarily, I am very impressed by how much cleaner it sounds. After some work with my Minidsp I got the delay set correctly and that really cleaned things up. According to REW in the 16hz tune I have usable bass down to nearly 12hz. I'm not going to complain about that.

I got the Ultra while in the middle of a move, so sadly I never got to play with it in my original theater, so I can't really say how much the Ultra added to the Plus. The new room is much larger (old theater was 12x10x8, the new theater is 17x11x11) so the Ultra is helping compensate for that. As of now I'll I've done in there is watched a few demo's of movies, tonight should be the first full length film in there.

Im running dual pb2000s in a room slightly bigger than that and it sounds damn good. Man I couldn't imagine how much better your setup sounds.

My twin SB13U are great - no complaints after the Anti-Mode. I think you may have mistaken my assistance and recommendation toward another fellow in the forum. 20 minutes is very reasonable for 8 measurements. I only measure my seat and I do keep YPAO activated after running the Anti-Mode on my subs - it's a huge difference without it and I verified my FR with REW and it's way more level and helps smooth the response. I enjoy YPAO : Flat the best as it keeps the highs sounding accurate, to my ears, and bright whereas Natural is more mellow and starts to dip around 11-12k.

Congrats, that must be amazing setup. I have chance to listen all 3 of those only 2 at time and end up with Pluses and it was not a plan at all. So with extra Ultra that must be excellent, enjoy.

Finally decided to pull the trigger on SVS PB-2000 soon. I had an old Cambridge Soundworks P-1000 dual 10" sealed, how much of a difference am I looking at between the two? Mainly movies for use some music.

My uncle has the CS P-1000 and IMO it's one of the most overpriced, over rated subs ever produced. I think the price tag was about $1000 on the thing and despite the solid reviews it got I always thought it was incredibly underwhelming. I had crappy $200-$300 subs back in the day like a 15" MTX and a 15" CV and both had more output than the P-1000. I'm not too familiar with the SVS PB-2000, but I'd imagine you'll experience a nice performance upgrade considering the ported design over sealed.

Got myself a PB-2000, had a hissing noise from the driver that I traced down to my Noma surge protector. There's no noise plugged directly to the wall though. Is there a certain type of surge protector that I need to get? The sub was the only thing I had plugged into it at the time, so I think the surge protector was generating some noise?

Hi everybody
I shall get PB-1000 in a week or two for my 19 x 9 x 9.5 feet room. For a couple of month can I place my centre speaker on top of it till my tv unit gets ready? I shall keep the volume low to moderate as other family members shall be around and also not to disturb the neighbour. Presently centre is placed on a small table and the table shall be replaced by subwoofer due to want of space.

I have a 7 year old PC-Ultra with the old BASH AMP. I have been upgrading components and decided I wanted dual subs. I like the PC-Ultra, but wanted to get away from the cylinder because I want to bring the subs on either side of the credenza and the tall cylinders would look odd. I did some experiments today with UMIK-1 and REW. I am new to this so was stumbling my way along. I would love dual PB-Ultas, but cost and size is an issue. I was thinking sealed, even though there are a tone of myths with sealed they would be a nice fit and allow me to stay with the Ultra driver. I enclosed some samples from my measurements and wanted some advice.

Disclaimer, Audyseey was run for the all ports open mode and I did not want to rerun it for each set up at this time. This experiment was more to see what FR I could get at what SPL from the sub in each mode. First observation I made was how damn clean the sub is, literally in every test the distortion on all of the first 10 harmonics was very low at even 20Hz. Second observation I made was that in sealed mode the PC-Ultra really extended very low down to 7Hz, but did have a dip in the 15-30Hz range. Also while Audyssey was not run for sealed it had one of the better looking FR graphs flatter with less radical swings. Will Audyssey be able to flatten that further making sealed very attractive?

My AVR is set for LPF on the sub at 120Hz and speakers are crossed at 100Hz, but why is the sub rolling off at 80Hz? I don't have any settings really set on the sub? The only setting I changed for each run was the mode 20/15/10/sealed setting to match the ports I had plugged.

I am also very disappointed in how erratic the all port open Audyssey curve is, so all over the place. Making me lean toward an external DSP for the subs.

Since I the all ports open mode could easily blast though 115db I wanted to see about getting 110db+ in sealed and it was OK but I had to crank REW from -10 to -3db (MAX) level and at around 4Hz the sub quit, blew the fuse. Clearly the BASH was not capable of giving any more. This was still hugely impressive since the sub is 7 years old and everyone has been ragging on the BASH AMPs. Fortunately I had the 2 spare fuses SVS shipped with the sub 7 years ago, swapped it out and back in business.

So seeing how the single PC Ultra did (corner loaded) in sealed mode, what opinions are there going to dual SB13-Ultra (not corner loaded)? Would I be able to make up for the dip in 15-30Hz range with Audyssey? Am I juts lost in the myths of sealed over ported? Any advice or opinions are welcome.

The dip at 100hz is probably because the sub is in anti phase with the mains. Add 5.6 feet to the sub distance in the manual settings of the avr and it should be phase matched. 5.6feet is halve the wave length of 100hz.
Phase matching is something only Audyssey Pro can do :-( But with rew and a mic you can tweak it yourselves.
